There were lots of great guesses from our Facebook fans this week, but only one is correct. If you said “Rocker Arm,” you got it. For the full, original image, see the pic below.

For more information, check out this Sealed Power Rocker Armon our site. For those who don’t know, we play Name That Part each Monday on our Facebook page. How it works: we post an image that reveals a small portion of an auto part, and our fans race to guess what it is. It’s a lot of fun and no major car knowledge is necessary to participate. (Although, it definitely helps!)
